EGO Power+ BSP3500 4 Gallon Backpack Sprayer – Cordless, 350 PSI, 0.6 GPM

Cordless spraying with power and precision

The EGO POWER+ 4 Gallon Backpack Sprayer BSP3500 combines a brushless motor and a lightweight design to deliver up to 350 PSI for a strong, even spray without pumping. The wand-integrated pressure dial lets you tailor pressure and flow on the fly, so you can adapt to different treatments without leaving the work area. With a maximum flow rate of 0.6 GPM, you can cover larger spaces efficiently while maintaining control over coverage.

Versatile spraying tools for varied tasks

Four included nozzles expand your toolkit for agricultural and horticultural tasks. The adjustable cone nozzle provides targeted application, the foaming nozzle creates sudsy coverage for certain treatments, the fan nozzle offers broad, even lines, and the shower nozzle delivers a gentle mist for delicate applications. You can switch between settings as needed to match your plants, pests, or fertilizer needs.

Designed for comfort during long sessions

The BSP3500 prioritizes ergonomics with premium back padding and waist straps, helping shoulders and hips bear the load more evenly during extended use. The translucent 4-gallon tank makes fill levels quick to assess, minimizing downtime. The 4-gallon capacity is paired with a durable build that’s rated IPX4 for weather resistance, so you can work in light rain or mist without worry.
